Abstract

Summary: Imino sulfonate PAGs sensitive to i‐ and g‐line were synthesized using 9‐fluorenone derivatives with arylethynyl units as starting materials. The PAGs exhibited good thermal stability and photoreactivity at 365 nm (i‐line) compared with that of an imino sulfonate PAG synthesized from unfunctionalized 9‐fluorenone. Evaluation of a series of i‐line sensitive PAGs were carried out. The PAGs were applicable to photocrosslinking of poly(glycidyl methacrylate) (PGMA). The PAGs were more sensitive than the PAG synthesized from unfunctionalized 9‐fluorenone.
